About Clefable... Why would you remove the Tank set? It doesn't play similar with the Wallbreaker at all.

Tank Clefable can still act as a special tank, and switch into many special attackers or special attacking walls, or even weak physical attackers such as Ferroseed, Mandibuzz, Munchlax, Qwilifish, Spiritomb and Steelix and either support the team (SR, Wish) or hit hard whatever comes in. It is basically a special tank that hits hard, and can support the team.

Wallbreaking Clefable on the other hand can't come into almost anything offensive, only on special attacking walls, can't support the team directly, and hits way harder with special moves, while also having way better coverage. It is basically one of the best wallbreakers that one could have against stall teams.

If you believe that removing a set is necessary (i don't), then the wall breaking set would be the best to get rid off, as it is very hard to use, as it can't come into much and is slow as hell. However it is exceptional against stall teams, ignoring passive damage, and being able to switch into many common walls. It is also able to dismantle the TanKing core, along with Steelix and Camerupt, and is generally very hard to wall. I don't think it should be removed, honestly, but i think it is the less viable of the sets.

Finally why would you remove Ferroseed from checks and counters? It set-up on support Clefable, and walls Tank Clefable if it doesn't have a fire move.

It is not only a matter of moves and spread (which are already enough reasons), but also a matter of how each set plays, and as i already explained they play very different.

Yeah i guess you are right about Ferroseed, but it still walls the Tank set if it lacks a fire move and the support set if it has Double-Edge/Facade, so it is a check i guess. Whatever, you decide what to do with Ferroseed, it is not rly important.

Finally i guess you are also right about GK. Fire Blast is very important in this meta as Escavalier, Steelix, Ferroseed, and ghosts are very important targets. It can go to AC, as not giving a chance to Omastar to set-up, while also ohkoing Kabutops and Rhydon is nice.

Added NU mons. Most of them like Wormadam and Tropius don't need to be changed, as they didn't gain anything from BW2 and still perform the same shitty jobs. You can just add stuff to Checks and Counters.

I'd argue that Seismitoad is RU-worthy. It is the fastest Swift Swimmer in the tier bar Kabutops, and can still outspeed base 100s with a Modest nature in the rain. It has STAB Hydro Pump and Earth Power, and while not as powerful as Omastar, it can really pack a punch. I'd say keep the analysis, even if it is never seen. It's one of rain's best sweepers, especially because of the Electric-immunity and lack of weaknesses.

The Pros and Cons of CB are pretty obvious to everyone, plenty of Pokemon can viably use CB and LO. I don't see why Primeape is any exception. Besides, anything that can spam U-Turn always has a strong case for running a CB set, and while I don't have any calcs to indicate such, I'm sure the power increase with CB will show with a banded Close Combat. The lack of LO recoil im sure is a big plus too
